Specific embodiment
Component of the present invention as the SSIPTS of change gearratio, electromechanical integration speed-changing driving device under a load
Operation therewith operates, and multiple pulleys including being divided into multistage, described section along rotation axis in the channel or
The path of toothed timing belt or chain (" annular construction member ") is moved to or moved away on guide rail.The SSIPTS's that the present invention operates
In context, this section and several sections of operations for briefly describing SSIPTS below.
In SSIPTS, as each section of multiple toothed pulleys concentrically and coaxially is arbitrary along passage or guide rail from it
One side is moved to or moves away the path of annular construction member in the axial direction, and the Timing System that is moved through of pulley segment is assisted
It adjusts, and the mobile engagement allowed between the multiple concentric pulleys of annular construction member change of coordination of pulley segment, without interrupting them
Rotation or power transmission.This is by enabling the tooth of annular construction member constantly to be engaged come real at least one toothed pulley
It is existing, and in the transfer, in some points (during when the engagement between annular construction member changes pulley), the tooth of annular construction member is made just to be connect
The engagement of both the pulley of conjunction and the pulley of positive separation.
By the way that some pulley segments is specified to be used as " key pulley segment ", first involved in the conversion from smaller pulley segment set
Beginning pulley segment is possibly realized with the last pulley segment involved in the conversion of smaller pulley segment set, the lasting engagement of formation is gone to.It closes
Key pulley segment is limited by the angular relationship of they and one or more smaller pulley segment sets so that the circumferential direction of key pulley segment
Position allows key pulley segment while annular construction member is still engaging the smaller pulley segment set to be engaged with annular construction member, and
Significant interference or relaxation are not introduced.
In SSIPTS, each pulley segment respectively by system actuator and from its unengaged position axially
It is moved to its bonding station and is axially moved to its unengaged position from its bonding station, such as pass through system sequencer
As control, which ensures to go to what is just engaged from the pulley segment set (" original group ") of positive separation in annular construction member
During pulley segment set (" purpose group "), to keep optimal order that annular construction member engages with not only one group of pulley segment and calmly
When, appropriate pulley segment is made to be moved to its unengaged position from its bonding station or be moved to it from its unengaged position and engages position
It puts.
Once key pulley segment is moved in its bonding station, then with it by " contact zone " (annular construction member with it is original
Angular contact area between group) outside, the pulley segment each followed in the same pulley segment set is subsequently moved to its engagement
In position.Therefore, the pulley segment followed continues that annular construction member is made to engage with purpose group.When pulley segment is in outside contact zone
Between during section, actuator with for each single pulley segment be enough to complete its between bonding station and its unengaged position along
The speed of the movement of either direction makes each single pulley segment movement.
The improvement characteristic of key pulley segment
A kind of method that pulley segment is designed as to key pulley segment is to make entire pulley segment set (together as the pulley of pulley
The ring that section is formed) it is rotated around rotation axis, until they are aligned in the circumferential compared with second pulley (or pulley segment set)
Only so that the tooth of key pulley segment and the second pulley is into distal relationship, so as to which annular construction member can simultaneously and key pulley segment
Tooth and second pulley indented joint.The main tooth with the pitch of the tooth of annular construction member and the second pulley of the distal relationship
Position it is related, the tooth of second pulley and the tooth of the key pulley segment are general tangential.
By pulley segment be designed as key pulley segment another method be shorten in pulley segment set engaging annular structure
In first tooth or pulley segment set of part engaging the last one tooth of annular construction member.This cunning that will allow in pulley segment set
Taking turns section becomes key pulley segment, and without rotating entire pulley segment set compared with another pulley or pulley segment set, this will make one
Multiple pulley segments in a pulley segment set can become key pulley segment.
With reference to figure 1, the shortening tooth 104 in key pulley segment 103 can be observed.It designs and shortens in key pulley segment 103
One potential problems of tooth 104 are exactly circularity when it may influence pulley segment set as pulley.To reduce change in shape
Change, the adjacent pulley segment 105 of key pulley segment 103 can be stretched so that the inward portion of flank profil (is located at the pulley segment
Tooth between " trench ") will extend towards key pulley segment 103.Elongation in this way, adjacent pulley segment 105 is towards institute
Key pulley segment 103 is stated to extend, it is recessed so as to be generated between the shortening tooth 104 of key pulley segment 103 and adjacent pulley segment 105
Paddy 106, when the position of the key pulley segment and the adjacent pulley segment all in their engageable annular construction members, institute
State trench 106 by support annular construction member towards between the pulley segment and the adjacent pulley segment space protrude that
A tooth.This extension of the adjacent pulley segment will ensure that pulley segment set is circular so that the annular construction member will be with owning
Pulley segment all smoothly cooperation cooperation, so as to prevent vibration and it is poorly efficient.
The combination of both design features, i.e. the shortening tooth 104 in existing key pulley segment 103, and have adjacent pulley
Elongation in section 105 generates trench 106 with the shortening tooth 104 with key pulley segment 103, and many pulley segments 48 is allowed to be designed to
Key pulley segment so that annular construction member can be converted to smaller pulley or pulley segment set from larger pulley segment set or from smaller
Pulley or pulley segment set be transformed into larger pulley segment set, and all without undesirable interference between any operating characteristics,
And there is no undesirable relaxation in annular construction member.Pass through pulley of the annular construction member to cooperation cooperation or cooperation from pulley segment set
The power transmission of the second pulley section group (the second example of SSIPTS) of cooperation can occur at high speed, this is because with annular
Component engages pulley segment set, can maintain the circularity of pulley segment set.
In addition, finishing tooth completely can be designed, to generate the support surface for annular construction member in key pulley segment.Now
With reference to figure 2a to 2c, the adjacent pulleys section 105 of elongation is shown, and pulley segment tooth 104 is trimmed, and in their position
Middle generation prevents the drastically curved support surface 159 of annular construction member 47.Support surface 159 is curved, and with this field
The arbitrary radius that technical staff defines.
The radius of support surface can be changed, to change the tooth of annular construction member to the tension of the tooth of pulley segment or removal not
Desired interference or relaxation, without changing the circumferential pass between two pulley segment sets (including original group and purpose group) in converting
System.
Another specific characteristic of key pulley segment operation is the elongation of adjacent pulley segment or overhanging tooth feature.With chain
The extension that adjacent pulley segment there can be the support surface with key pulley segment to coordinate in a sliding manner is taken turns, is come so as to receive
From the radial support of key pulley segment.The overhanging tooth of adjacent pulleys section instead of shortening in foregoing key pulley segment or
" missing " tooth modified completely, and pulley segment set is completed by doing so so that the tooth not lacked, and pulley segment set
All sections all in bonding station.
Overhanging section of tooth and the geometrical relationship of support surface can make the operation optimization of key pulley segment.Key pulley segment
Support surface and overhanging tooth can have for the pieceable circular or partial cylindrical surface of annular construction member.In order to make key pulley
The support surface of section support surface and overhanging tooth will not become to block in the torsion of annular construction member or unjustified situation or beam
It ties up, a support surface or two support surfaces can have the feature for isolating contact point so that the support surface will not fetter
Together.This feature can be designed by those skilled in the art, and may include processing protuberance, tubercle or track or it is multiple on
The feature stated or its combination etc..
The construction and implementation that alternative pulley segment stacks
Multiple pulley segments during pulley segment stacks may be designed as moving together.In this case, different pulley segment set
Pulley segment closer to each other can fuse, bond, connect or be configured as the stacking that an object activated and (" stack connection
Fit (unified stack) ").Fig. 3 to 7 shows the construction of the stacking association and the different views of operation.
The pulley segment stacked in association can be interleaved so that is moved when stacking association along the rotation axis of pulley assembly
When dynamic, any one in the pulley segment all can be at its bonding station.Fig. 3 a and 3b provide what staggeredly pulley segment stacked
Two normal axomometric drawings.Different pulley segment sets is connected or is constructed together close to vertical pulley segment as stacking association
150.Pulley segment tooth 52 keeps available, to engage ring when stacking association 150 will it is expected that pulley segment 48 is moved to bonding station
The tooth of shape component.When pulley segment is moved to its bonding station, entire stack is moved, so as to before in stacking in engagement
The pulley segment of position must be moved away from bonding station simultaneously.In this embodiment, mobile stacking association causes this
The section engagement in the pulley segment of association is stacked, necessarily implies that another mobile stacking so that the section of its engagement previous
Separation.
Stack association its " downward " or radial direction " interior " surface on, on the surface of the rotation axis closest to pulley assembly
One group of guide rail is set on " downward " of pulley segment upper, in minimum pulley segment set or radial direction " interior " side, faces rotation axis.Heap
Folded association also can be its " upward " or radially on " outer " surface, on the surface farthest away from rotation axis, in maximum pulley segment
One group of guide rail is set on " upward " of group or radially " outer " side, back to rotation axis.
Pulley assembly has the mating feature for receiving the interior guide rail, and assembles conjunction with described the another of outer guide is received
Feature so as to keep the stacking association compared with pulley assembly, while allows to stack association in itself and pulley assembly
It is moved in the parallel guide rail group of rotation axis, the pulley segment stacked in association is thus allowed to be moved to or move away it each
Bonding station.The guide rail and the mating feature in the stacking association of pulley assembly can eliminate the transverse direction to pulley segment
The demand of passage or track on face or side, and the outer guide on the outermost of pulley assembly can be eliminated to core pulley
Demand and effect, as in this embodiment, minimum pulley segment set becomes " first gear ".Fig. 3 a and 3b show outer match somebody with somebody
Close feature 151 and interior mating feature 152.The embodiment allows pulley segment by sturdy and durable to accommodate and (it is rotary to be gathered in list
On one unilateral side of the annular construction member of conveyer belt (single carousel) formula, this is passed with the dual rotation type in other embodiments
Send band (dual-carousel) alignment opposite.
Fig. 4 is shown as staggeredly pulley segment stacks the normal axomometric drawing of pulley assembly of the association in gear shift.Pulley segment
48 are arranged to multiple stacking associations 150 staggeredly, wherein have fit on feature 151 and interior mating feature 152, together with mounted on
Guide rail 153 on core pulley 154, core pulley 154 are itself mounted on the axis 32 of pulley assembly.
Fig. 5 is shown as staggeredly pulley segment stacks the side view of pulley assembly of the association in gearshift.Fig. 5 is depicted
The driving pulley component 155b and follow-up pulley component 155a being installed on axis 32.Staggeredly pulley segment stacking association 150 can
Further be specially it is each stacking association 150a to 150j (from view, stack association 150d to 150g be occluded, and
It is not shown).Stack the second small pulley segment in association 150c, 150d, 150e, 150f, 150g, 150h, 150i and 150j
48 in the bonding station with annular construction member 47, and stacks the 3rd small pulley segment in association 150a and have just moved into engagement position
It puts, and stacks the 3rd small pulley segment in association 150b and activated and be just moved to bonding station.In this example, heap
The 3rd small pulley segment is key pulley segment in folded association 150a, and therefore engages annular construction member 47 first in its group.
Fig. 6 shows three views of pulley assembly, wherein currently staggeredly pulley segment is stacked in the form of " second gear "
Engagement.
Key pulley segment can entirely or and arbitrary number in association can not be stacked entirely in one stacks association
Purpose pulley segment can be key pulley segment.Stacking association and can be free of has key pulley segment.
Core pulley can have can be with the tooth of the indented joint of annular construction member so that the tooth on core pulley also acts as center
The track with the neighbouring interior guide rail cooperation for stacking association of hub.Fig. 7 shows guide rail 153 and mating feature 153, such as in core
Observed by pulley 154.
SSIPTS system actuators are individually or in conjunction with SSIPTS systems sequencer together using indexing system
(indexing system), ratchet system or other systems are moved axially to association is stacked or move away relatively
In the position in the path of annular construction member, so that each pulley segment in the stacking association can move on to its bonding station.
The pulley segment of stacking containing the pulley segment from each pulley segment set can vertically be divided into one or more stackings
Association.For example, if vertical 8 independent pulley segments for being grouped into a stacking association are for rail system or other systems
It has difficulties, then can it is expected to be divided into includes two son stackings of four vertical adjacent segments.In this example, 8 are being used
In the SSIPTS of pulley segment set, the pulley segment from four minimum pulley segment sets may together form to be operated by an actuator mechanism
A stacking association, and the pulley segment from four maximum pulley segment sets can be configured to be grasped by the second actuator mechanism together
Second made stacks association.
Major advantage using the embodiment for stacking association is, reduces the number of actuator, but this field skill
Art personnel can assess the characteristic of intensity, weight, size and operability.
Design with roller and cam
By independent pulley segment set into pulley segment stack association can be moved so that the arbitrary pulley segment wherein contained can
Bonding station (" stacking axial movement ") is moved to or moves away by cam or roller camming.In this configuration, often
A joint pulley segment, which stacks, all has roller, and the roller is by roller arm or other supporting members and slidably or with rotatable
Mode be attached to the stacking.The roller can also be fixing component or other such be lubricated or by people in the art
Cam-follower made of the material that member selects for its intensity, abrasion and frictional behavior, but it is hereafter referred to as " roller ".
One or more cams are incorporated into the operation of SSIPTS, and wherein cam is fixed on or in a manner of fixable
Mounted on chassis or housing, and in the region that pulley segment does not engage with annular construction member (regions of SSIPTS " contact zone " outside,
It can be described as " relief area ").In relief area, the engageable roller of cam, and joined by engaging to stack and mobile pulley section
Zoarium, so that each pulley segment of the stacking is moved to or moves away bonding station.
Cam can axial direction or linear array installation or can by position it is interchangeable one or more cams in the form of
It sets.One or more cams can be installed in a movable manner, be moved axially so as to which it be allowed to adapt to several stack.
Roller can be moved to or move away the position of one (" roller activated positon ") in its engagement cam compared with stacking.
Roller can be mounted on roller arm or other moveable supporting members, guided between roller activated positon and its un-activated position
Roller.The supporting member is hereinafter referred to as " roller arm ".The quality of roller and roller arm can be put down compared with rotating or sliding axis
Weighing apparatus so that centripetal force will pro, negatively or be neutrally acted on the position of roller, as those skilled in the art preferentially recognize
For as.
It is observed referring now to Figure 8, a series of pulley segment stacks association 150 with cam 156, a series of roller
157 and roller arm 158, wherein roller arm 158a, 158b, 158c, 158d and 158e are in roller activated positon, roller arm 158f, 158g and
158h is in roller un-activated position.
When the pulley segment of stacking is in SSIPTS " contact zone ", roller is movable to roller activated positon so that begins to stack up
